T0 at whom it may concern.-

Be it known that I, WILEY BRENTON, a citizen of the United States, andaresident of Carlisle, in the county of Sullivan and State of Indiana,have made certain new and useful Improvements in Threshing-Machines, ofwhich the following is a specification.

My invention is an improvement in threshing-machines and it consists incertain novel constructions and combinations of parts hereinafterdescribed and claimed. w Referring to the drawings forming a parthereof, Figure 1 is a longitudinal section of a threshing-machineprovided with my improvement. able bearings for the toothed cylinders,and Fig. 3 is a side elevation showing the arrangement of the gearingfor driving the different parts.

In the practical application of my invention I provide a framework A,comprising longitudinal bars a, the cross-bars a, and the uprights o Theuprights a are suitably connected by cross-bars a at the top, and theframework is supplied with suitable side coverings a and a covering forthe top a. A cylinder B of ordinary construction is suitably journaledin the sides ofthe frame, and below the cylinder is arranged a concaveC,

also of ordinary construction and suitably supported by the sides of theframe. An endless apron D, supported by rollers d, mounted on the shaftsd, journaled in the sides of the frame, is arranged below the cylinderto the rear thereof and inclined upwardly at a slight angle therefrom.Coacting with the upper surface of the endless apron are a plurality oftoothed cylinders E, each rotating in the same direction with the uppersurface of the belt and at a slightly increased speed. The cylinders Eare mounted upon the shafts e, journaled in adjustable bearings e in thesides of the frame, and are shown in the present instance as three innumber. A second endless apron F, supported by rollers f, mounted uponthe shafts f journaled in the sides of the frame, is arranged beneaththe rear end of the firstnamed endless apron and spaced apart slightlytherefrom a suflicient distance to allow of the passage of grain betweenthe adjacent ends of the aprons, yet near enough to receive the strawdelivered by the first apron. Cylinders G G, supported by the shafts g gjournaled in adjustable bearings g in the sides of the frame, arearranged above the Fig. 2 is a detail of the adjustendless apron F forcoacting with the upper run thereof. The cylinder G is arranged torotate in an opposite direction to the travel of the upper run of theendless apron F, while the cylinders G are arranged to travel in thesame direction with the said upper run. A floored grain-board H, havingan upwardlycurved rear end h, is arranged beneath the lower run of theendless apron F for receiving the threshed grain from the endless apronand guiding the same onto a riddle K, a grain-board 7c being arranged atthe front of the riddle and projecting upwardly to guide the grainfalling between the adjacent ends of the aprons onto the riddle.

A shoe M, suspended by the rods or links m from the sides of the frameand driven bya pitman 'm from a transverse crank-shaft m at the rear ofthe machine, is arranged below the riddle for receiving the grainpassing therethrough. The shoe, however, forms no part of my presentinvention, and I have not deemed it necessary to further describe thesame.

A screw conveyer N of ordinary construction is arran ed transversely ofthe machine beneath the forward end of the shoe for conveying the cleangrain from the machine. A transverse check-board O is arrangedapproximately centrally of the shoe, and to the rear of the check-boardand beneath the shoe is arranged a second screw conveyer P for conveyingthe tailings to the elevator Q, by which they are returned into themachine for a second cleaning.

The first apron B is inclined upwardly only enough to receive theforward end of the second apron thereunder, and a straw-carrier ofordinary construction may be arranged to the rear of the second apron toreceive the threshed straw and to convey the same from the machine.

The bearings e of the cylinders E and the bearings g of the cylinders GG are adjustable to and from the upper run of the apron, this adjustmentbeing shown in Fig. 2. The bearing comprises upper and lower sections 66 secured together by bolts e and normally upheld in the guides c e bythe springs 6 a screw-threaded bolt 6 traversing an opening in theguide-frame and swiveled to the bearing-section 6 being provided forraising and lowering the same.

A fan R is arranged to the forward end of the shoe for forcing a currentof air therethrough toward the rear of the machine, the

IIO

fan and shoe being operated by means of suitable bands connected tomoving parts of the machine.

For convenience in operating the parts of my improved threshing-machineI preferably make use of the construction and arrangement ofbelt-gearing shown in Fig. 3, the operation of which will be clearlyunderstood from the drawings in connection with the arrows thereon.

In operation the straw or grain is passed by the cylinder onto theendless apron and is moved toward the rear of the machine, the cylinderE agitating the straw and dislodging the grain during its passage. Atthe end of the conveyer the dislodged grain falls between the apronsupon the riddle, while the straw passes upon the upper surface of thecylinder G and between the cylinders G G to the endless apron F,where itis agitated a second time. The threshed grain falls from the endlessapron F onto the grain-board and fiilom thence through the riddle andinto the s oe.

It will be evident from the description that by the use of my inventionthe machine may be made lighter and of smaller size than existingmachines. All shakers and crankshafts being dispensed with, the machinewill be smoother in operation, less noisy, and more durable.

My invention is capable of use in machines for threshing wheat, barley,rye, oats, or clover. 7

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a threshing-machine, the combination of a frame, a cylinderjournaled in the frame, a concave supported below the cylinder, anendless apron supported behind and beneath the cylinder and inclinedupwardly with respect thereto, means for moving the apron, a pluralityof toothed cylinders journaled in the frame above the apron andcooperating with the upper run thereof, means for adjusting thecylinders to and from the apron, means for rotating the cylinders in thesame direction as the upper run of the apron and at a higher rate ofspeed, a second endless apron supported beneath the first apron, andspaced apart longitudinally therefrom, a

grain-board beneath the apron, means for moving the apron, a toothedcylinder journaled above the second apron and cooperating with the upperrun thereof, means for adjusting the cylinder to and from the apron,means for rotating the cylinder in a direction opposite to the movementof the upper run of the apron, and at a higher rate of speed, aplurality of toothed cylinders journaled behind the first cylinder andcooperating with the upper run of the apron, means for rotating thecylinders in the same direction as the upper run of the apron, and at ahigher rate of speed, means for adjusting the cylinders to and from theapron, a riddle beneath the adjacent ends of the aprons, a grain-boardsecured to the forward end of the riddle, a shoe beneath the riddle,means for vibrating the shoe, and means for operating the parts insynchronism and in timed relation with each other.

2. In a threshing-machine, the combination of a frame, a cylinderjournaled in the frame, an endless apron supported below the cylinderand inclined with respect thereto, means for moving the apron, aplurality of toothed cylinders cooperating with the upper run of theapron, means for rotating the cylinders in the same direction as themovement of the upper run of the apron and at a higher rate of speed, asecond endless apron supported beneath the first apron and spaced apartlongitudinally therefrom, a grain-board beneath the apron, means formoving the second apron, a toothed cylinder supported above the secondapron and cooperating with the upper run thereof, means for rotating thecylinder in a direction opposite to the movement of the upper run of theapron, and at a higher rate of speed, a second cylinder behind the firstcylinder and cooperating with the upper run of the apron, means forrotating the second cylinder in the direction of movementof the upperrun of the apron, and at a higher rate of speed, a vibrating shoe belowthe apron, means for vibrating the shoe, and means for actuating theparts in timed relation with respect to each other.
